That is interesting, I have zero love for the FoxPro remote. I hate having to read the screen. The only FP remote I like is the TX-500/505 with the numeric keypad, I can just punch in the call number I want either off the list or on the preset, I hardly have to look at the thing on a stand.
My favorite remote was the Minaska remote and set it up with rodent sounds and pup distress on the same keys of every bank so I had those available with what ever sound I was using.
